Thanks for that Cindy - the USU error log was already set to false - I'll keep an eye out for updates

Just wondering if you have any thoughts on the relationship of USU to SitemapXML with the issue I have in sitemaps submitting standard cPath urls and not USU urls and with no canonical links? - Google doesn't (can't) index them! - thread >> https://www.zen-cart.com/showthread....56#post1351156

thanks again for your assistance,
cheers Mike
